Abstract (en)
A hydroponic growing system (20) comprises an elongated preferably rectangular hollow trough (22) having substantially closed sidewalls and bottom and an open top defining a central space. The trough defines a pair of spaced tracks extending the length thereof in the space and an elongated flexible strip (46) is slideably disposed in the tracks. The strip contains a plurality of spaced apertures extending vertically therethrough along the length thereof and in each aperture is disposed a plant growing cup (50) having a hollow body defining a central space, an open top, a porous bottom and substantially closed or perforated sidewalls The sidewalls bear outwardly extending peripheral supports so that the body of the cup extends down into the trough space and the cup is releasably held in position by the support bearing on the upper face of the strip. <??>The trough may include an internal conduit with spaced openings (78) to supply hydroponic makeup fluid (68) to the trough space. The trough includes spaced hydroponic fluid exits (80) for removal of hydroponic fluid. The system is used by growing plants from seeds to seedlings in the cups, then inserting the cups through the strips into the trough and continuing hydroponic growing therein with periodic harvesting of the grown plants (72) at the downstream end of the trough together with periodic addition of seedling plans in cups to the upstream end of the trough.
